I am using Visual Studio 2008 and created a simple ASPX page with two drop downs in it. I am using the Update Panel so that when any item is seleted in drop down 1 the second drop down selected item will change accordingly.
I was hoping the update panel will not fix the page refreshing but I am not sure what is wrong since I still see the Page refresh.
see the code below I am using.

I am trying to use the update panel for the drop down to avoid page refresh and this is not working for me...I am using VS 2008.
what I am missing here....I have tried using AJAX script manager as well as AJAX Tool Kit script maanger and none is working.
<
form
id="form1"
runat="server">
<div>
<asp:ToolkitScriptManager
[Code]....
Am using update panel in my .aspx page .when i change the value in drop down list inside the update panel am getting the following error. am not using any response object or server object in my code.
"Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error ...."
I have a user control in a master page with two drop down lists. When the user selects an item out of either ddl, I want to load a specific user control inside an update panel on the content page. I can't figure out how to get the user control to trigger the update panel.
Master
<%@ Register src="toolbar.ascx" tagname="toolbar" tagprefix="uc1" %>
<head id="Head1" runat="server">
</head>
<body>
[Code]....
i am confused about the fact that if partial update of dropdowns is possible through Update Panel ,then why we should use asp.net ajax Cascading drop down extender ,that has made same task bit complex by making callback to web services ? what is difference between using update panel and cascading drop down extender ?
View 2 RepliesI'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.
I have the following scenarion. I have a range of drop down menus where a clietn can select. The code below is wrapped in an update panel but without this, the button click fires a method to retrieve the number of products. So for example, an item is selected from ddlCategory, the btnValidate is clicked and the label returns the number of products within that category.I have the following code for an update panel - I'm just not sure how to implement if effectively.
<asp:UpdatePanel ID="UpdatePanel1" runat="Server">
<ContentTemplate>
<asp:Label ID="lblSearchResultsStatus" runat="server" Text="Number of results found: "></asp:Label>
<asp:Label ID="lblSearchResults1" runat="server" Text=""></asp:Label>
<br />
<br />
<asp:Button ID="btnValidate" runat="server" Text="Validate Search"
OnClick="btnValidate_Click" Width="120px" />
</ContentTemplate>
</asp:UpdatePanel>
How do I go about wiring the update panel so that when a drop down list item is selected, the buttong is effectively clicked?

I have a problem doing a partial page post back with an update panel within a tab container.
I am adding the control programmatically as follows
[Code]....
The controls are added to the tab container but the button now causes a full page postback. The button_click event is no longer called. Is there something I am missing here.

I have a facebook app with an asp.net update panel. It works fine when running outside facebook, how ever once I run the app in Facebook the update panel stops working. I check the javascript console and found the following errors were occuring.
Uncaught Sys.WebForms.PageRequestManagerParserErrorException: Sys.WebForms.PageRequestManagerParserErrorException
The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
I have following code and when I select from my drop down list the progress controls do not show and my grdiview is not being filled either. If I leave out the update panel from my code things are working fine.

I have an Ajax timer that has an interval of 1 second and an update panel on my page. If I leave the page open and never close or refresh I notice that after 6 to 8 hours the timer stops firing. No error messages.......everything just stops. If I refresh the page everything starts working again. Are there any issues I am not aware of when running a page for a long time using the Ajax timer?
